Signatures are an outdated concept that hold no bearing to forum conversations, but are given to people anyways to make them feel special and unique when in reality, they are special and unique, no matter if they have a signature or not.

This is handled by entity inputs and outputs - for example, if you want to open a door when a control point is capped, you'd go into the outputs of the team_control_point, and add a new one: OnCappedTeam2/3 [2 is red, 3 is blu] some_door_name Open.
